What are the main characteristics of Dodecyl polyoxyethylene ether AC-1202?

Dodecyl polyoxyethylene ether AC-1202 is a nonionic surfactant prepared by ethoxylation of fatty primary amines, exhibiting cationic properties in acidic media and possessing multiple functions such as emulsifying, wetting, and dispersing.

Detailed Description

Dodecyl polyoxyethylene ether AC-1202 (also known as: Laureth-2, AEO-2, CAS number: 26635-75-6) belongs to nonionic surfactants, but its unique molecular structure allows it to exhibit cationic properties under acidic conditions, thus combining the dual functions of nonionic and cationic surfactants. This characteristic endows the product with extremely wide application flexibility, suitable for various complex industrial formulation systems.

The product appearance is a colorless to slightly yellow transparent liquid with good fluidity, easy to handle and compound. Its molecular structure contains both polyoxyethylene ether segments and amine functional groups, allowing it to exhibit differentiated surface activity behaviors under different pH environments, and can adapt to various working conditions such as acid, alkali, and hard water without hydrolysis or deactivation.

This product has high chemical stability, good compatibility with various auxiliaries, and can be freely compounded with nonionic, cationic, and amphoteric surfactants. It is widely used in fields such as pesticide emulsification, textile printing and dyeing, industrial cleaning, metalworking fluids, leather degreasing, and paint dispersion.

Core Characteristics

Application Suggestions

Based on its multiple characteristics, AC-1202 has outstanding application value in the following fields:

• Pesticide emulsifier: Used in formulations of emulsifiable concentrates, microemulsions, and emulsion concentrates to improve emulsification dispersion performance and permeability, enhancing efficacy.
• Textile printing and dyeing auxiliaries: Used as an antistatic agent and soft finishing agent to eliminate fiber static electricity, improve fabric hand feel, and enhance leveling.
• Industrial cleaners: Excellent wetting, penetrating, and degreasing ability, suitable for heavy oil stain hard surface cleaning and metal parts cleaning.
• Metalworking fluids: Provides emulsifying, lubricating, and anti-rust auxiliary functions in cutting fluid and grinding fluid formulations.
• Leather degreasing agents: Quickly penetrates and removes natural fat from raw hides, ensuring uniform degreasing without damaging the leather surface.
• Paint dispersants: Prevents pigment particle flocculation and sedimentation through steric hindrance effect, ensuring stable storage of color paints.

Precautions

• The product is flammable, store in a cool, dry, and well-ventilated place, away from strong oxidizers and heat sources, storage temperature should be maintained at 5～35°C.
• It is recommended to wear chemical safety goggles and impermeable gloves (such as nitrile rubber) during operation, avoid direct contact with eyes and skin.
• Use as soon as possible after opening, seal and store unused product, shelf life is two years from the date of production.
• The product exhibits cationic properties under acidic conditions, and this characteristic can be fully utilized in formulation design.
